Amazon S3 and S3 Compatible Object Storage Considerations and Limitations
General Limitations
Consider the following limitations:
- Make sure that you add an S3 compatible object storage device fully compatible with the AWS S3 operations and AWS S3 Signature Version 4 standard.
- For some S3 compatible object storage repositories we do not recommended to use more than one bucket for each scale-out backup repository. If you use multiple folders within one bucket for several scale-out backup repositories, it will slow down data processing since the metadata generated by S3 compatible is handled for each bucket. To check requirements for your object storage, contact your S3 compatible vendor.
- [For Amazon S3] Only the Standard, Standard-IA and One Zone-IA storage classes are supported. For more information about Amazon S3 storage classes, see AWS Documentation.
- S3 compatible storage systems with the eventual data consistency model are not supported.
- To be able to work with S3 compatible with Data Archiving object storage, the SOSAPI functionality must be enabled. To enable this, contact your S3 compatible vendor.
Considerations and Limitations for S3 Compatible Repositories with Multiple Buckets
Consider the following limitations:
- If you add S3 compatible repositories with multiple buckets as capacity extents, Veeam Backup & Replication will ignore this setup and will store backups in the master bucket.
- Once you enable the multiple bucket option for S3 compatible object storage repositories, you will not be able to convert these repositories back to a single bucket repository.
- After you enable the multiple bucket option for existing S3 compatible object storage repositories, the existing backups will still be located in the master bucket. All new backups will be stored in child buckets.
- Child buckets are not displayed in the UI. You can access them using UI of your S3 compatible object storage vendor.
- You cannot use a child bucket to configure another S3 compatible object storage repository.
- Veeam Backup & Replication keeps configuration backups in a separate location and ignores multiple bucket setup.
